I found the game enjoyable, but really frustrating at the same time.
I think the fact that the skills are hidden is more of a hindrance than a challenge, and not very fun.
Also, I think the re-spawning could use a little tweaking. I instinctively always pressed Z (a default button in many games) after dying, which meant I fell through the floor to my death yet again !
But I still found the game quite addictive.
This is how far I could make it this time.
But I’ll say that the game-mechanics are quite unique, so I’d encourage further development if you’re motivated.
BTW, the “pass-through-walls”-mechanics yielded some quite interesting results.
I’m not quite sure was I supposed to be able to do this?
Cheers!
